Help with C++ Problem. The Program is working and doing all that it should, but in order for the pair, twopairs, three of kind, fourofkind, flush and straight functions to work in main is if they take in a paramater. How can i make it so these functions dont need to have a parameter? Thank you for your help and tips.
